Disturbed areas other than the locations described above for which the Steep Slope Variance applies <br />were backfilled and graded to the Approximate Original Contour. <br />A detailed slope stability analysis for the access road fill and the portal fill at the South Portal is <br />provided in Appendix 14-8 of the PAP. A cross-section L-L' of the lower parking area, Access Road <br />1 A, and the reclaimed slope above the new access road is shown on Exhibit 26. As shown in the <br />cross-section the slope above the new access road was reclaimed to an approximate 2:1 slope. This <br />was verified with field measurements using an inclinometer. An inclinometer was used to field check <br />gradients at various locations. A representative slope of 40% was measured at the north end of the <br />parking area on the reclaimed slope north of the access road, a slope of 50% was measured on the <br />slope below the access road between the upper bench and Pond 8, and a slope of 46% was measured <br />on the new portal fill. <br />In early 2008 a drainage pipe that extends out of the sealed South Portal had begun to leak at some <br />point following the sealing of the pipe with 6 cubic yards of grout. The pipe was inspected by DRMS <br />with Tonya Hammond of SCC in April 2008. The drainage from the pipe flowed down a ditch to <br />Pond 8. The estimated flow from the pipe was less than 1 gpm. Subsequently, SCC submitted <br />Technical Revision No. 56 (TR-56) to provide a plan to completely seal the pipe. The proposed plan <br />was to cap off the end of the pipe and encase it in approximately one cubic yard of concrete. TR-56 <br />was approved in May 2008 and the pipe has been sealed in accordance with the approved plan. SCC <br />capped off the end of the pipe and encased it in approximately two cubic yards of concrete. The site <br />was then backfilled. The repair was successful and the pipe is no longer leaking and the location is <br />dry and stable. The South Portal drainage pipe repair location is shown in the attached Photograph <br />No. 4 that was taken during an inspection of the repair work in May 2008. <br />The site of the A Substation and the two locations on either side of the Colorado River where the <br />overland conveyor tube/bridge structure had been removed and associated areas regraded were found <br />to be stable and revegetated with no signs of erosion or other problems identified. See the attached <br />Photograph Numbers 5 and 6 of the A Substation and the location on the east side of the river where <br />the overland conveyor tube/bridge structure has been removed, respectively. <br />One access road is located in the bond release request area and is shown in the permit application <br />package (PAP) on Exhibit 6C, Roadside South Portal Post Mining Topography. Access Road #IA <br />was approved as a permanent road with PR-3 and is discussed on page 13-3 of Tab 13 in the PAP. A <br />cross-section is provided on Exhibit 26. The surface of the road is gravel and the width is 20 feet. <br />The road is well constructed and found to be in good condition (see attached Photograph No. 7). <br />One light use road (Light Use Road #1) was included in the bond release area. This road has been <br />fully reclaimed. The reclaimed portion of which is shown on Exhibit 6C located on either side of the <br />RSRDA Borrow Area. The road surface was covered with topsoil and the road surface reseeded. The <br />road was reclaimed to conform to adjacent terrain and blend with the natural contour. The site of the <br />reclaimed road was stable with no signs of erosion. The reclaimed light use road site is shown in <br />Photograph Numbers 8 and 9. Cheat grass has become well established in this location. <br />Page 7
